An allergic reaction to oysters or other shellfish can cause swollen lips.
Swollen lips are usually the result of allergic reactions. These allergic reactions can lead to a condition that causes short-term swelling below the surface of the skin, a condition known as angioedema. Puffy or swollen lips can also be caused by other conditions, such as infection, injury, or certain hereditary conditions.
Lip swelling is one of the most typical symptoms of angioedema. It often occurs when a person has some type of allergic reaction. Allergic reactions can occur as a result of certain foods, medications, the environment, or insect bites. When the body comes into contact with these allergens, a chemical called histamine is released. Histamines cause the body to react in a way that can result in swollen lips.
An injury to the mouth area can cause the lips to swell.
Common food allergies include peanuts, dairy, and shellfish, although any type of food can cause an allergic reaction. Apart from swollen lips, a person may also experience itchiness around the mouth. When swelling of the lips occurs after taking medications, it can be a cause for concern. This is a sign that the person is having an allergic response to the medication they have taken and can occur even if the person has previously taken the medication without any problems. If a person’s lips begin to swell after taking medication, they should see a doctor.
Environmental allergens can cause swollen lips and sneezing.
Environmental allergies that can cause lip swelling are often the same allergens that cause hay fever and other allergic reactions. In addition to sneezing, itchy eyes and a runny nose, pollen and fungus in the air can also cause swollen lips. Other environmental sources that can cause lip swelling include house dust and pet hair, or flaky skin.
An infection can cause the lips to become swollen and swollen.
Hereditary angioedema is an immune disorder that causes swelling of the face, including the lips. The swollen lips of this condition can be caused by illness or certain medical procedures. A person with this condition must pay close attention to their breathing when they notice that they have swollen lips. Difficulty breathing can be the result of inflammation of the airways and cutting off the air supply.
An allergic reaction to toothpaste can cause swollen lips.
During the healing process after lip surgery, the lips often have a puffy appearance. This is not uncommon and will eventually return to normal. A swollen lip can also indicate an infection, especially if the area is hot or feels swollen. Injuries, such as getting hit in the mouth or having a cut or piercing in the lip, can also cause the lip to swell.
